The CM-SAM9X25 CPU module integrates an AT91SAM9X25 microcontroller operating at 400MHz, with external 128MByte DDR2 SDRAM, 256MByte Nand Flash, and 4Kbit EEPROM. Peripheral functions, including UART, Ethernet, USB, SDIO, JTAG, CAN, Soft Modem, SPI and all I/Os are brought out by two B-to-B 100-pin female connectors. This is the same CPU module that comes mounted on the NET-SAM9X25 development board. To mount it on your own system, your system will need a pair of AMP 5179030-4 100-pin connectors.

The module comes with Linux 2.6.39 installed, and operates in the industrial temperature range of -40°C to +85°C. The 8-layer PCB measures 57 × 39 mm.
